Application filed July 2 1,

To all whom it may concern.

Be it known that I, DANIEL D. SMITH a citizen of the United States, residing at Valdosta, in the county of Lowndes, ntate of Georgia, have invented av new and useful Powder Duster; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to powder dusters, and has for its object to provide a device of this character, which may beeasily carried and operated by one hand of an operator, provided with means whereby powder may be intermittently dusted from the device as desired, thereby allowing a single operator to operate two machines at the same time if desired, for depositing powder on adjacent rows of plants; The device is particularly adapted for use in depositing powder on cotton plants for killing boll weevil, however it is to be understood that the device may be used in connection with various kinds of plants.

A further object is to provide a hand op erated powder dusting device comprising a casing having its lower end open and a powder receiving bag disposed therein. 1 The handle member for the" casing is provided. with lever and flexible connections with a weight in the bottom of the bagj which weight upon the operation of the device is intermittently raised and allowed to lower, thereby not only mixing the powder within the bag, but upon the lowering operation powder is dusted through the bag, and onto plants beneath the device.

A further object is to provide a wire mesh screen at the lower end of the casing for preventing portions of the; plant from coming in contact with the bag. Also to provide a. screen or shield extending entirely around the lower end of the casing for preventing powder as it is dusted from the devicet'rom being blown away from the lant.

With the above and otherobjec-ts in view the invention resides in the combination and arrangement of parts a hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings 1 Figure l is a perspective view of the powder duster.

Figure 2 i a vertical transverse sectional View through the lower end of the duster.

Figure 3 is a detail perspective view of a portion of one of the arms of the U-shaped handle member, showing the lever pivoted thereto.

teterring to the drawing, the numeral 1 designates the rectangular shaped casing of the powder dusting machine and 2 ii U-shapcd handle member, which extends upwardly and has, its arm 3 secured to the opposite sides of the casing 1. Although the casing 1 has been described as rectangular shaped, it may be round or any other shape desired. Disposed within the casing 1 is a powder receiving bag 1, which is formed from fabric and preferably from gauze, through which powder may easily pass upon a jolt-ing of the bag 1-. The bag 4L has upper end secured to the casing 1 by means of removable cleats 5, therefore the bag may be easily removed when it is desired to replace the same with another bag. Secured in the lower end of the bag a is a weight 6, which may be of any shape desired, however for purposes of illustration it i shown as spherical shaped. 'During the operation of the device, the weight 6' is intermittently raised and allowed to drop for jolting the bag 4 and consequently causing powder within the bag 4: to sieve through the bag. Upon the upward movement of the weight 6, it will be seen that powder within the bag 4 will be agitated as the mixing operation takes place, and consequently the powder is thoroughly mixed during the operation of the device.

In operation the operator grasps the transverse portion 7 of the handle member and places his thumb on the member 8 of the vertically movable and guidable rod 9, forces said rod downwardly and then re leases the same. The lower end of the rod 9 is pivotally connected at 10 to a rock lever 11, which rock lever has the transversely disposed portion 12 rockably mounted in one of the arms 3 of the U-shaped handle member, therefore it will be seen that after the lever 11 is formed from a single straight piece of material passed through the arm 3 and bent at 13, the lever 11 will be positively held on the arm 3 and pivot bolts eliminated, thereby reducing the working parts to a minimum. Connected at 14 to the inner end of the lever 11 is a flexible member 15, which member extends downwardly into the bag 4 and is connected at 16 to the weight 6, consequently it will be seen that upon downward movement of the rod 9, the weight 6 will be raised and when the rod 9 is released, said weight will drop, thereby imparting a jolt-ing action on the fabric bag 4 and dusting powder therefrom. The lower end of the casing 1 is provided with a screen 17 which screen prevents parts of the plants, when the device is disposed thereover, from entering the casing 1 and interfering with the jolting operation. To prevent powder as it is being dusted, tron] blowing away from the plants, the lower end of the casing l is provided with a shield 18, into which the upper ends of the plants may be received during a powder dusting operation.

From the above it will be seen that a hand operated powder dusting machine is provided, which machine is simple in construction and may be easily and quickly operated by one hand of the operator, and powder intermittently dusted therefrom by the intermittent raising and lowering of a weight carried by the powder bag. It will also be seen that'the rod Sis guided in its vertical movement by an eye 19 carried by one of the arms 3', consequently the finger engaging member 8 is held adjacent the hand engaging-portion 7 of the handle member;

The invent-ion having been set forth what is claimed as new and useful is 1. The combination witha powder dusting'machine comprising a casing, a powder bag disposed therein a weight carried by said bag, a handle memberextending npwardly from said casmg, of means for intermlttently raising and dropping said weight, saidmeans comprising a lever rockably'mounted on thehandle member and havin one of its. arms disposed over the bag, a fiexlble member connecting said lever and said weight a vertically movable rod connected to said lever said rod terminating adJacent the upper end oi the handle member.

2. The combination with a hand operated powder dusting machine comprising a cas ing, a powder bag disposed withm thecasing, a weight carried by said powder bag, means tor intermittently movlng the bag, of a screen carried by the. low end of the casing below the bag, and a windshielc and cas-

carried by the lower endot' the casing extending below said lower end of the ing. V

3. A hand operated powder dusting inachine comprising a casing having its lower end open, a screen carried by said lower end. a fabric powder receivingbag disposed within the casing, a weight carriedby said bag the upper end of said bag being de-.

' handle member.
